A highly potent form of marijuana, in which the end, smokable product contains no seeds.

Sensimilla does not refer to a particular breed or strain of plant. Any female marijuana plant which is prevented from becoming fertilized will produce flowers without seeds. This contributes to a higher THC content in the harvest because none of the buds have had a chance to turn into seeds. This also contributes to the quality and rarity of Sensimilla product because an unfertilized sensi-yeilding plant is unable to reproduce (until fertilized).

The term "Sensimilla" is broken down to translate in Spanish as "without seeds" (sin semilla), however the term was coined and popularized in the context of marijuana culture by California growing regions. (which have strong Spanish/Mexican cultural influence)

"I also got a lot of aid from good good sensimilla
that's why I do not snort the coke I only burn the Ganja."
-Pato Banton

sensimilla is when any breed of marijuana is kept from being fertilized. Some plants have a strong tendency to be hermapradites and are harder to keep from being fertilized. If there was a breed that just did not have seeds, how would it reproduce?

Seedless marijuana, from the Spanish "Without seeds". Originating in California. Yes California, which isn't were Spanish originated, but neither is Mexico, you moron. California has an enormous Spanish speaking population which you know unless you've lived your life locked in a cupboard under the stairs in South Dakota. 9.9

High potency weed, originally got its name in California, where the science of growing seedless marijuana evolved, but spread out across the country. Sensemilla is now just seedless marijuana, doesnt have to be from California
